As many times as I hang up fishing timber I can't see using two jigs. That said, I was fishing minnows the other day and had multiple crappie chasing the one I had hooked around because the minnow had slid up the line. I think a jig above or below the minnow would work when they are doing that. I didn't try it as minnows like to tangle up too much and I hate tangles.
John 21:3 Simon Peter saith unto them, I go a fishing. They say unto him, We also go with thee.
